Practice aid. Pitch follows A4 = 440 Hz (ISO 16:1975) in equal temperament; clicks are timed on the audio clock, and your device adds a fixed output delay. Checked 2026-10-23. ISO 16:1975 · Disclaimer
Tap the squares to place hits, press Play. Presets give you a starting groove; the tempo and timing come from the same engine as the metronome.
How to program a beat
Each row is a drum, each column a sixteenth note: four columns make one beat. A basic rock beat puts the kick on 1 and 3 (columns 1 and 9), the snare on 2 and 4 (columns 5 and 13) and the closed hi-hat on every eighth note.
Swing delays every second sixteenth. 0 % is straight; around 60 % gives a shuffle feel.
